Photogrammetry is a solution that integrates several technologies, in order to obtain three-dimensional terrain models (3D) as well as an orthophoto (2D) free of errors for planimetric analysis, all of this accurately georeferenced, both in a global and local system. Advantages: The execution time of a project in the field is considerably reduced, approximately 25% Extensive surveys. Terrain representativeness. Remote work, which allows operators to be away from risky areas (falls, machinery traffic, etc.). Productivity and effectiveness. Necessary information: photographs obtained by UAV and GNSS observation files + post-processing software.
